And if that’s not enough of a challenge, you can also try to close a Captains of Crush No. 3.5 and No. 4 gripper under official conditions; women can square off with a Captains of Crush No. 2 or a No. 2.5 gripper (not yet done by any woman in the world).

The IronMind booth (adjacent to the Odd Haugen Strength Classic, which features strongman, mas wrestling and grip strength competitions) will also offer official attempts to complete the Crushed-To-Dust! Challenge, so here’s your chance to get certified on this test of all-around grip strength excellence.

Close a Captains of Crush No. 2 gripper, lift 45 lb. (20 kg) on the IronMind Hub, and 200 lb. (90 kg) on the Rolling Thunder—that’s the Crushed-To-Dust! Challenge, a benchmark test of all-around strength excellence.
